JavaScript string

JavaScript strings are used to store and process text.

JavaScript string

A string can store a series of characters, such as "JohnDoe".

The string can be any character inserted in quotation marks. You can use single or double quotation marks:

Example

Varcarname= "VolvoXC60"

Varcarname='VolvoXC60'

You can use the index position to access each character in the string:

Example

Varcharacter=carname [7]

The index of the string starts at 0, which means that the first character index value is [0], the second is [1], and so on.

You can use quotation marks in a string, and the quotation marks in the string should not be the same as those in the string:

Example

Varanswer= "It'salright"

Varanswer= "Heiscalled'Johnny'"

Varanswer='Heiscalled "Johnny"'

You can also add escape characters to the string to use quotation marks:

Example

Varx='It\ 'salright'

Vary= "Heiscalled\" Johnny\ ""
